MSN search engine

I did have, I think, Google as a web browser In Internet Explorer (7?) and used MSN as my home page. Does this make sense? I hope you understand because I do not. I have since changed it and some setting in Cclean. I now have MSN browser I would like to go back to the way it was. I don't think many people use MSN as a browser, also I have lost all my top lines with my favourites tools help File Edit etc and the beat goes on. any help please before I turn in for the night? I will be able to sleep if I know I have got everything back the way it was.
